Storage-specific host prep

iSCSI hosts

Set-Service MSiSCSI -StartupType Automatic; Start-Service MSiSCSI
New-IscsiTargetPortal -TargetPortalAddress $iSCSIPortal
Get-IscsiTarget | Connect-IscsiTarget -IsPersistent $true -IsMultipathEnabled $true

FC hosts

Mask same LUNs to all 4 FC hosts (identical LUN IDs).
Confirm Get-Disk shows them on all nodes before clustering.

SMB 3.0 hosts

On SOFS: ensure shares are Continuously Available and grant Full Control to host computer accounts and VMM-SVC.

Approach 1: Build Windows clusters first, then import into VMM

iSCSI cluster

Test-Cluster -Node $Hosts_iSCSI -Include 'Inventory','Network','Storage'
New-Cluster -Name $CluName_iSCSI -Node $Hosts_iSCSI -StaticAddress $CluIP_iSCSI -NoStorage
Set-ClusterQuorum -FileShareWitness $WitnessShare

# Add & convert all LUNs to CSV
Get-ClusterAvailableDisk | Add-ClusterDisk
Get-ClusterResource | ? ResourceType -eq 'Physical Disk' | % { Add-ClusterSharedVolume -Name $_.Name }

# Optional: tag networks (names must match your cluster networks)
(Get-ClusterNetwork 'StorageNet').Role = 1     # ClusterOnly
(Get-ClusterNetwork 'LiveMigrationNet').Role = 3
(Get-ClusterNetwork 'ManagementNet').Role = 3

FC cluster

Test-Cluster -Node $Hosts_FC -Include 'Inventory','Network','Storage'
New-Cluster -Name $CluName_FC -Node $Hosts_FC -StaticAddress $CluIP_FC -NoStorage
Set-ClusterQuorum -FileShareWitness $WitnessShare

Get-ClusterAvailableDisk | Add-ClusterDisk
Get-ClusterResource | ? ResourceType -eq 'Physical Disk' | % { Add-ClusterSharedVolume -Name $_.Name }

(Get-ClusterNetwork 'StorageNet').Role = 1
(Get-ClusterNetwork 'LiveMigrationNet').Role = 3
(Get-ClusterNetwork 'ManagementNet').Role = 3

SMB 3.0 cluster (no CSV)

Test-Cluster -Node $Hosts_SMB -Include 'Inventory','Network'
New-Cluster -Name $CluName_SMB -Node $Hosts_SMB -StaticAddress $CluIP_SMB -NoStorage
Set-ClusterQuorum -FileShareWitness $WitnessShare

(Get-ClusterNetwork 'StorageNet').Role = 1
(Get-ClusterNetwork 'LiveMigrationNet').Role = 3
(Get-ClusterNetwork 'ManagementNet').Role = 3

Import clusters into VMM

Console path: Fabric → Servers → Add Resources → Hyper-V Hosts and Clusters → Windows Server computers in a trusted AD domain → add the hosts (VMM discovers their clusters) → pick Host Group → Finish.

(PowerShell skeleton)

Import-Module VirtualMachineManager
$vmm   = Get-SCVMMServer -ComputerName $VMMServer
$runAs = Get-SCRunAsAccount -VMMServer $vmm | ? {$_.Name -eq $RunAsName}

# Add at least 2 nodes per cluster (discovery will bring in the cluster object)
$Hosts_iSCSI | % { Add-SCVMHost -VMMServer $vmm -ComputerName $_ -Credential $runAs }
$Hosts_FC    | % { Add-SCVMHost -VMMServer $vmm -ComputerName $_ -Credential $runAs }
$Hosts_SMB   | % { Add-SCVMHost -VMMServer $vmm -ComputerName $_ -Credential $runAs }

Build everything from inside VMM

Add standalone hosts to VMM (Fabric → Add Resources).
Fabric → Create Host Cluster (run 3 times: iSCSI, FC, SMB): pick 4 hosts, set Cluster Name/IP, wizard runs validation, select storage (LUNs for iSCSI/FC → CSV; Shares for SMB), done.

(PowerShell to add hosts is the same as above; the Create Host Cluster wizard is the most reliable path in 2012 R2).

VMM Fabric — one-time build (PowerShell)

This creates Logical Networks + Sites, IP Pools, Classifications, Uplink Profiles, and a Logical Switch you can apply to each host.

Storage in VMM

iSCSI/FC: Fabric → Storage → Providers → add SMI-S provider; classify tiers (Gold/ Silver). Allocate LUNs to each cluster → they appear as CSV under the cluster in VMM.
SMB: Fabric → Storage → File Servers → add SOFS01 → add HVShare1/2 → assign access to the SMB cluster hosts.

Fast validation

# Create a test VM on CSV (iSCSI/FC cluster example)
New-VM -Name 'TestVM01' -MemoryStartupBytes 2GB -Generation 2 `
  -Path 'C:\ClusterStorage\Volume1\VMs\TestVM01' -SwitchName $ProdVSwitch
New-VHD -Path 'C:\ClusterStorage\Volume1\VMs\TestVM01\TestVM01.vhdx' -SizeBytes 60GB -Dynamic
Add-VMHardDiskDrive -VMName 'TestVM01' -Path 'C:\ClusterStorage\Volume1\VMs\TestVM01\TestVM01.vhdx'
Start-VM TestVM01
Move-ClusterVirtualMachineRole -Name 'TestVM01' -Node (Get-ClusterNode | ? {$_.State -eq 'Up'} | Select -First 1 -Skip 1).Name

For SMB cluster, place the VM path on \\SOFS01\HVShare1\VMs\... and repeat.

One-page Ops & Gotchas

AD permissions: Pre-stage CNOs or grant hosts (or VMM-SVC) Create Computer Objects on the hosts’ OU.
CSV format on 2012 R2: NTFS (don’t use early ReFS for Hyper-V).
AV exclusions: C:\ClusterStorage\, Hyper-V processes, and VM file types.
Live Migration: Compression (default above). Use RDMA/SMB LM only if end-to-end supported.
MPIO: Confirm recommended policy from your storage vendor; verify pathing per node.
SMB shares: Must be Continuously Available; perms to computer accounts + VMM-SVC.
CAU: Use Cluster-Aware Updating (or VMM Servicing) to patch with zero/low downtime.
Recovery: Clear-ClusterDiskReservation -All if disks stuck; remove bad resources and re-add.
